[lldb-dev] How do I use lit to only run the lldb test suite, now that dotest multiprocessing capabilities have been removed?

[Jonas Devlieghere via lldb-dev]

Hey Ted,

1. You can run just the dotest-tests by pointing lit at the
`lit/Suite` directory.
2. You can pass arguments to dotest by passing `dotest-args` in --param.

The invocation would look something like this:

/path/to/llvm/bin/llvm-lit /path/to/lldb/lit/Suite --param
'dotest-args=--foo --bar'

Hope that helps,
Jonas

In these runs we don’t care about the lit tests or the unit tests, because they are OS agnostic. We do this by specifying the compiler, lldb, and test flavor (static testcase + os, dynamic library testcase loaded by an OS image, dynamic library testcase loaded by an OS image running the OS’ debug stub).
